era_py
Helpers for the Python port of Empirical Research in Accounting: Tools and Methods.
Install
pip install era-py
pip install "era-py[polars]"
pip install "era-py[tables]"
For repository development, prefer the checked-in virtual environment:
.venv/bin/python -m pytest
era-py provides two import paths:
import era_pyis the base API built around pandas/Ibis-style workflows.import era_plis the Polars API and requirespip install "era-py[polars]".
Usage
from era_py import load_data, ols_dropcollinear
camp = load_data("camp_attendance")
Testing Optional Dependencies
For quick checks of optional extras without changing your local environment, use
uv run --with ...:
PYTHONPATH=src uv run --with polars python -c "import era_pl; print(era_pl.__version__)"
This is useful for verifying the era_pl import path and other Polars-specific
behavior without permanently installing polars into your project environment.
